API Rate Limit Illustration for Options：

Future, Coin Margined Swap,Option Swap and USDT Margined Swap are using separate API rate limits.

Please note that, for both public interface and private interface, there are rate limits, more details are as below:

• Generally, the private interface rate limit of API key is at most 48 times every 3 seconds for each UID (Trade Interface: at most 24 times every 3 seconds. Read Interface: at most 24 times every 3 seconds) (this rate limit is shared by all the altcoins contracts delivered by different date). API Interface List

• For public interface used to get information of index, price limit, settlement, delivery, open positions and so on, the rate limit is 60 times every 3 second at most for each IP (this 60 times every 3 second public interface rate limit is shared by all the requests from that IP of non-marketing information, like above).

• In terms of public interface used to get candle chart data, the latest transaction record and information of aggregate market, order book and so on, the rate limit is as below:

  (1) For restful interfaces：all products(futures, coin margined swap, usdt margined swap and option) 800 times/second for one IP at most

  （2）For websocket: The rate limit for “req” request is 50 times at once. No limit for “sub” request as the data will be pushed by sever voluntarily.

• WebSocket, the private order push interface, requires API KEY Verification:

  Each UID can build at most create 30 WS connections for private order push at the same time. For each account, contracts of the same underlying coin only need to subscribe one WS order push, e.g. users only need to create one WS order push connection for BTC Contract which will automatically push orders of BTC-USDT contracts. Please note that the rate limit of WS order push and RESTFUL private interface are separated from each other, with no relations.

• Both read and trade interfaces will return the ratelimit info.You can refer to the following fields of "header" from api response. E.g.,you will get the total Read ratelimit("ratelimit-limit") and the remaining Read ratelimit("ratelimit-remaining") when you query the order info(/option-api/v1/option_account_info) , and you will get the total Trade ratelimit("ratelimit-limit") and the remaining Trade ratelimit("ratelimit-remaining") when you place an order(/option-api/v1/option_order)). API Interface List

• Will response following string for "header" via api

  ratelimit-limit: the upper limit of requests per time, unit: time

  ratelimit-interval: reset interval (reset the number of request), unit: ms

  ratelimit-remaining: the left available request number for this round, unit: time

  ratelimit-reset: upper limit of reset time used to reset request number, unit: ms
